Question

A motorcycle travels a distance of 420 miles in 8.5 hours. Give the average speed of the motorcycle

Answer 1

As per Provided Information

Distance travelled by motorcycle is 420 miles

Time taken by motorcycle is 8.5 hours

we have been asked to determine the average speed of the motorcycle .

`\bf \: Speed_((Average)) = \cfrac{total \: distance \: travelled}{time \: taken}`

Now let's put the given value to find the average speed of motorcycle

`\longrightarrow \sf \: Speed_((Average)) \: = \cfrac{420}{8.5} \\ \\ \\ \longrightarrow \sf \: Speed_((Average)) \: = \cfrac{4200}{85} \\ \\ \\ \longrightarrow \sf \: Speed_((Average)) \: = \cancel\cfrac{4200}{85} \\ \\ \\ \longrightarrow \sf \: Speed_((Average)) \: = 49.41 \: miles \: per \: hour`

Therefore,

• Average speed of the motorcycle is 49.41 miles per hour .
