Question

a car travels 80 km in 2 hours it will travel how many km in 5 hours with uniform speed​

Answer 1

Answer:

200KM

Step-by-step explanation:

v=80/2 = 40

S=vt = 40 x 5 = 200KM

Answer 2

Answer:

A car travels 80 km in 2 hours. What is its speed?

We know

SPEED=DISTANCE/TIME

DISTANCE=80KM

TIME=2HRS

SO

WE PUT THE FORMULA

SPEED=80KM/2HR=40KM/HR(ANS)

A car travels 100km. The journey takes 2 hours. The highest speed of the car is 80km/h, and the lowest speed is 40km/H. What is the average speed for the journey?

It’s highest and lowest speed is irrelevant.

Average speed is simply distance over time so it was 50km/h

A car travel 30 km in 1 hour, and 40 km in 2 hours. What is the average speed?

The question can be interpreted as

Total Distance =40 km, of which 30 km covered in first hour, remaining 10 km covered in another hour

Av speed= 40/2= 20 km/hr

Or

2. Total distance= 40 km, 30 km in 1 hr, remaining 10 km in 2 hrs

Av speed = 40/3= 13.33333.. km/hr

Or

3. Total distance= 70 km, 30 km in first hr, 40 km in second hr

Av speed= 70/3= 23.3333.. km/hr
