Question

Jamal is 8 miles away from his house. He rides his bike home toward home at a speed of 12 mph.. How far away from home is he after a half hour? 1 mile 2 miles 3 miles 4 miles

Answer 1

Answer:

2 Miles

Explanation:
Since he is going 12 miles per hour he would be going 6 miles half an hour meaning if he is 8 miles away and he was biking towards home for half an hour at 12 mph, he would end up 2 miles away.

Answer 2

Given:

Distance- 8 miles, Speed: 12 mph

To find:

How far is Jamal after 30 mins/half hour?

Explanation:

• Speed is a scalar quantity which can be defined as distance covered per unit time.
• With the help of this information the distance can be calculated if the speed and time is known.
• In this question Jamal is going home with the constant speed of 12 mph  and in time half hour.

• So to calculate the covered distance, the equation used is: Speed = $\frac{Distance}{Time}$ (inserting the given values)

• 12 mph = $\frac{x}{0.5}$
• x= 6 mph
• The distance travelled in half hour is 6 miles.
• The distance need to be travelled = 8 - 6 miles = 2 miles.
• Hence, Jamal is 2 miles far away from his home after half hour
