Calculating Speed

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time

Front

If a robot chases you at a speed of 900 m/s for a distance of 180 m, how do you calculate the time taken?

Back

Time = Distance / Speed = 180 m / 900 m/s = 0.2 s

Front

How far does Shona travel if she cycles at an average speed of 8 km/h for 4 hours?

Back

Distance = Speed x Time = 8 km/h x 4 h = 32 km

Front

What is the relationship between speed, distance, and time?

Back

Speed is the rate at which distance is covered over time.

Front

If a car travels at 30 miles/hr for 3 hours, how do you calculate the distance traveled?

Back

Distance = Speed x Time = 30 miles/hr x 3 hr = 90 miles

Front

What is the time taken to travel 100 miles at a speed of 50 miles per hour?

Back

Time = Distance / Speed = 100 miles / 50 miles/hr = 2 hours

Front

How far can Kermit travel in 2 hours at a constant speed of 12 miles per hour?

Back

Distance = Speed x Time = 12 miles/hr x 2 hr = 24 miles

Front

What units are commonly used to measure speed?

Back

Common units include meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph).

Front

How do you convert kilometers per hour to meters per second?

Back

To convert km/h to m/s, divide the speed by 3.6.

Front

What is the average speed if a vehicle travels 150 miles in 3 hours?

Back

Average Speed = Total Distance / Total Time = 150 miles / 3 hours = 50 miles/hr.
