You can bicycle 5 mi in 40 min. At that rate, how long does it take to travel 18 miles?

144 minutes

Step-by-step explanation:

Let the time taken be A

Since you can ride 5 miles in 40 mins

Therefore,

5 miles = 40 mins

18 miles = A mins

Cross multiply

A x 5 = 18 x 40

5A = 720

Divide both sides by 5

5A/5 = 720/5

A = 144 mins

At that rate, it'll take 144 minutes to travel 18 miles

2 hours 24 min

Step-by-step explanation:

Or 144 minutes
