Question

Andre rode his bike at a constant speed. He rode 1 mile in 5 minutes.

Which of these equations represents the amount of time t (in minutes) that it takes him to ride a distance of d miles?
A - T = 5d
B - T = 1/5 d
C - T = d+4
D - T = d-4

Answer 1

Explanation:

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

Hence find answer will be equation t=5d.
