Question

Aliyah left the airport and traveled home at an average speed of 40 km/h.

Shanice left at the same time and traveled in the opposite direction with an
average speed of 60 km/h. How long does Shanice need to travel before they are
300 km apart?

Answer 1

Time = 3 hours

Explanation:

The total speed is,

→ 40 km/h + 60 km/h

→ 100 km/h

Formula we use,

→ v = d/t

Then the time taken will be,

→ v = d/t

→ 100 = 300/t

→ 100 × t = 300

→ t = 300/100

→ [ t = 3 ]

Hence, answer is 3 hours.

Answer 2

• 3 hours

Explanation:

When moving in opposite directions from the same point the speeds add up.

Total speed:

• 60 + 40 = 100 km/h

Distance is 300 km, find the time.

• time = distance / speed

• t = 300/100
• t = 3 hours
