Question

The maximum speed in Charlie's grocery is 380 km/h. A train can travel at a speed of 873×10² km/h. What is the greatest number of kilometers the train can travel in 16 hours? Express your answer in scientific notation.

Answer 1

The train can travel a maximum distance of 1.3968 × 10^5 km in 16 hours.

Step-by-step explanation:

To find the greatest number of kilometers the train can travel in 16 hours, we need to multiply the speed of the train by the time it travels. The speed of the train is given as 873×10² km/h, and the time is 16 hours.

So, the distance the train can travel in 16 hours is:

Distance = Speed * Time

Distance = (873×10² km/h) * (16 hours)

Distance = 13968×10² km

Simplifying this expression gives:

Distance = 1.3968 × 10^5 km

Therefore, the greatest number of kilometers the train can travel in 16 hours is 1.3968 × 10^5 km.
