How do you convert time to distance?
You can use the equivalent formula d = rt which means distance equals rate times time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
How do you find change in distance?
Rate of change in position, or speed, is equal to distance traveled divided by time. To solve for time, divide the distance traveled by the rate.
How do you calculate the number of minutes in a question?
Count the number of short questions and divide the remaining time by the number of questions. So, if there are 50, that would give you just over 1½ minutes per question.

How do you calculate conversion rate?
Conversion rates are calculated by simply taking the number of conversions and dividing that by the number of total ad interactions that can be tracked to a conversion during the same time period. For example, if you had 50 conversions from 1,000 interactions, your conversion rate would be 5%, since 50 ÷ 1,000 = 5%.
How do you convert miles per hour to minutes per mile?
To convert from mph into minutes per mile we need to divide 60 by the number of miles per hour. So 12 mph = 5 minutes per mile.
How do you find time when given speed and distance?
For example, if the distance is given in km and time in hr, then as per the formula: Speed = Distance/ Time; the units of speed will become km/ hr.
What is the total distance divided by time?
Average speed is the total distance traveled divided by the elapsed time. (Average speed is not the magnitude of the average velocity.)
How do you calculate 30 minutes payroll?
Converting minutes to decimals for payroll is simple. All you need to do is divide your minutes by 60.
