Question

The spine-tailed swift and the frigate bird are the two fastest birds on earth.A frigate bird can fly 95 miles per hour , which is 11 miles per hour slower than a spine-tailed swift. How fast can a spine-tailed swift fly

Answer 1

a spine-tailed swift can fly at a speed of 106 miles per hour

Explanation:

to simplify the statement we are going to represent what the problem says as an equation

f = frigate bird speed = 95 mi/h

s = spine-tailed speed = ?

f = s - 11mi/h

95 mi/h = s - 11mi/h

95 mi/h + 11 mi/h = s

106 mi/h = s

a spine-tailed swift can fly at a speed of 106 miles per hour
