Andre rode his bike at a constant speed. He rode 2 1/3 miles in 11 2/3 minutes.

(a) Write an equation that represents the distance d he rides (in miles) after time t (in minutes) passes.
(b) How long will it take Andre to ride 4 2/5 miles?

Respuesta :

Given that Andre rode his bike at a constant speed.
Number of miles driven = 1 mile
Time taken to drive 1 mile = 5 minutes.
Then speed can be calculated using formula:
Speed = Distance / Time


Now we have to find the amount of time t (in minutes) taken by him to right distance d so we can again use same formula.

Speed = Distance / Time
or
Time = Distance / Speed
Plug the given values

t = 5d
