Question

A Cat Moves 30km East and 40km north in 2 hours

What is
a. the total distance
b. the total displacement
C. Speed
S. Averege Velocit

Answer 1

Step 1: Given data:

Speed of the car for first 30km = 40 km/h

Speed of the car for next 30km = 20 km/h

Step 2: Calculation of the average speed of the car:

We know,

Averagespeed=TotaldistancetravelledTotaltimetaken

Time taken to travel the first 30 Km = 30km40 km/hr=0.75hr

Time taken to travel the next 30 km = 30km20km/hr=1.5hr

Now,

Total distance travelled = 30km + 30km = 60 km

Total time taken = 0.75hr + 1.5hr = 2.25 hr

Thus,

Averagespeed=60km2.25hr

Averagespeed=26.66kmh−1

Hence,

The average speed of the car is 26.66kmh−1 .
