Question

the speed of a car going 50 miles in one half hour (0.5 hour)

Answer 1

Answer:

50/.5 miles per hour

100 miles/hour

Answer 2

Given:

The Distance travelled by the car is $d = 50 mile$

Time taken by the car to travel is $t=0.5 h$

To Find:

Speed of the car $(v)$

Step by Step Explanation:

Speed is given by  $Speed(v)=\frac{Distance(d)}{Time(t)}$

Speed in miles per hour(mph) is

$v=\frac{50}{0.5}=100mph$

Speed in kilometer per hour(kmph) is

$1 mile = 1.6 km$  

∴ $50 mile=50\times1.6 =80km$

∴ $Speed(v)=\frac{80}{0.5} =160kmph$            

Answer:

$100mph (or)160kph$
