Answer:
Step-by-step explanation:
1. Formula: d = s x t
Solution: d = 40 km/hr x 3 hours
= 120 km
2. Formula: s = d/t
Solution: s = 20 km / 4 hours
= 5 km/hr
3. Formula: s = d/t
Solution: s = 520 km / 8 hours
= 65 km/hr
4. Formula: d = s x t
Solution: d = 18 km/hr x 2 hours
= 36 km
5. Formula: t = d/s
Solution: t = 90 miles / 20 mph
= 4.5 hours
