Issac drove the first three hours at 44 miles per hour.
Step-by-step explanation:
Given,
Average speed of Isaac = 49 mph
Let,
x be the speed during last three hours.
Speed during first three hours = 4x-172
Average = 
Multiplying both sides by 2
Dividing both sides by 5
Speed during last three hours = x = 54 mph
Speed during first three hours = 4x-172 = 4(54)-172 = 216-172 = 44 mph
Issac drove the first three hours at 44 miles per hour.

The maximum and minimum distance from Earth to the Sun are 94.5million miles and 91.4million miles respectively.
Given that the average distance from Earth to the Sun is 92.95 million miles, if the actual distance varies from the average by up to 1.55 million miles, the then;
- Maximum distance = average distance + variation
- Minimum distance = average distance - variation
Maximum distance = 92.95 million + 1.55million
Maximum distance = 94.5million miles
Minimum distance = 92.95 million - 1.55million
Minimum distance = 91.4million miles
Hence the maximum and minimum distance from Earth to the Sun are 94.5million miles and 91.4million miles respectively.
