Question

1.Jim traveled at a speed of 18 km/h for 90 minutes. What was the distance covered?

2. In a cycle race, a cyclist is moving with a speed of 2 km/hr. He has to cover a distance of 5 km. Calculate the time he need to reach his destiny.

3. How far will you travel if you walk for 150 minutes at 6km/h? 

​

Answer 1

Answer:

Most people regularly walk around 5 kilometers an hour. Assuming you're in no hurry, and the terrain is flat, and you were capable of walking at a constant rate for the better part of a day, you should be able to cover 100km in around20 hours.

Answer 2

Answer:

1.Given

• Speed of Jim = 18km/h
• Time = 90min = 90/60hours = 3/2hours

To find

• Distance travelled by Jim

Solution

$distance = speed \times time$

Substituting the value

$distance = 18 \times \frac{3}{2} \\ distance = 9 \times 3 \\ = 27km$

Hence, the distance travelled by Jim with the speed of 18km/h in 90 min is 27km.

2.Given

• Distance travelled = 5km
• Speed = 2km/h

To find

• time taken by the cyclist

Solution

$time \: taken = \frac{distance}{speed}$

Subtituting the value

$time \: taken \: = \frac{5}{2} kmh {}^{ - 1} \\ = 2.5kmh {}^{ - 1}$

3.Given

• Time = 150min = 150/60 hours = 5/2 hours
• Speed = 6km/h

To find

• Distance covered

Solution

$distance \: = time \times speed$

Substituting the value

$distance \: = \frac{5}{2} \times 6 \\ = 5 \times 3 \\ = 15km$
