The plane travelling at a speed of 300 mph will travel 90 miles in 18 minutes.
A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.
Given that, a plane travels 300 mph,
That means, its unit rate is 300 mph
Therefore, in 60 minutes it will travel 300 miles
Therefore, in 1 minute it will travel = 300 / 60 = 5 miles
Thus, in 18 minutes it will travel = 5 x 18 = 90 miles
Hence, the plane travelling at a speed of 300 mph will travel 90 miles in 18 minutes.
