Question

A bicyclist going 35 mph can make it from 1st Street to the Boston Eatery in 45 minutes. How long (in minutes and seconds) will it take a motorcyclist going 40 mph?

Answer 1

39.375 minutes

formula's:

distance = speed * time taken

time taken = distance/speed

speed = distance/time taken

here given:

• speed: 35 mph

• time = 45 minutes = 0.75 hours

solve for distance:

• distance = 35 * 0.75

• distance = 26.25 miles

1st Street to the Boston Eatery distance is 26.25 miles, which is constant.

If speed changes to 40 mph.

• time taken = distance/speed

• time taken = 26.25/40

• time taken= 0.65625 hours = 39.375 minutes
