Answer 2

To find:

The distance covered by a car in one hour that covers $\bf115\frac{1}{2}$ distance in $\bf2\frac{2}{3}$ hours.

Solution:

Change the fraction in improper fraction.

$\bf115\frac{1}{2}$=$\bf\frac{231}{2}$km

$\bf2\frac{2}{3}$ = $\bf\frac{7}{3}$hours.

Distance covered by the car in $\bf\frac{7}{3}$hours=$\bf\frac{231}{2}$Km

Distance covered by the car in 1 hour=$\bf\frac{231}{2}÷\frac{7}{3}$

=$\bf\frac{231}{2}×\frac{3}{7}$

=$\bf\frac{33×3}{2}$

=$\frac{99}{2}$

=$\bf{49}\frac{1}{2}$ km.

Therefore,The car will cover $\bf{49}\frac{1}{2}$ km in 1 hour.
