Question

A car travels $130$ km in $2\frac{1}{2}$ hours.
a. Find the time required to travel $240$ km
b. Find the distance traveled in $3$ hours

Answer 1

Time taken to distance covered $130$ km$=\frac{5}{2}$hrs

time taken to distance covered in $1$ km$=\frac{1\times \frac{5}{2}}{130}$

$=\frac{60}{13}$hr

$=4$ hr $36$ sec (approx.)

a) time required for $240$kms

$=240\times \frac{60}{13}$

$=156.92$hrs.

b) distance covered in $1$hr $=\frac{130}{2.5}$

distance covered in $3$ hr $=216$km
