Question

A car travels 2 (5/8) miles 3 (1/2) minutes at a constant speed. How far did the car travel in 5 minutes?

Answer 1

Answer:

3.74 miles

Step-by-step explanation:

Given that,

Distance, $d=2\dfrac{5}{8}\ \text{miles}=\dfrac{21}{8}\ \text{miles}$

Time, $t=3\dfrac{1}{2}\ \min=\dfrac{7}{2}\ \min$

We need to find how much the car will travel in 5 minutes.

$\dfrac{21}{8}\ miles = \dfrac{7}{2}\ min\\\\1\ min= \dfrac{21\times 2}{8\times 7}\\\\=0.75\ \text{miles}\\\\\text{In 5 minutes}, d = 0.75\times 5\\\\=3.75\ \text{miles}$

Hence, the car will cover 3.74 miles in 5 minutes.
