Answer:
7.5 hours (7 hours and 30 minutes)
Step-by-step explanation:
ok Let's start with 64km/h.
1.6 km=1 mile,
64÷1.6=40miles
so 64km/h changes into 40miles/hour.
Zebras's round trip =300miles,
300/40=7.5
so answer is 7.5 hours.
x ≤ -259/9
Change into a number equation 9(x + 26) ≤ -25
443.28
Subtract 42.24 from 570.3 three times.
