Question

A car travels 80 km in 2 and a half hours. what is its speed in km per hour?

Answer 1

Answer:

speed = 32 kmph

Step-by-step explanation:

A car travels 80 km in 2 and a half hours.

=> distance = 80 km

=> time = 2¹/₂ hours = $\frac{5}{2} \ hours$

$speed = \frac{distance}{time} \\\\ => speed = \frac{80 \ km}{\frac{5}{2} \ hours } \\\\ => speed = \frac{(80)(2)}{5} \\\\=>speed=\frac{160}{5} \\\\=> speed = 32 \ kmph$
