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

Answer 1

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

$Speed = 1 / 5$

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

$Time = \frac{d}{\frac{1}{5}}$

t = 5d

Hence find answer will be equation t=5d.
