Answer:
The mean amount of time it takes people in her town to travel to work and towns= (t₁+t₂)/2
Step-by-step explanation:
Total population is 150000
Adult population is 90,000
The population for the old and kids will be 15000-90000=60000
Assume distance to town is D
Assume the speed taken by adults to travel to town is S₁ and that of the remaining group is S₂, then the time taken for travel will be;
Adults=D/S₁=t₁
Others =D/S₂=t₂
The mean amount of time it takes people in her town to travel to work and towns= (t₁+t₂)/2
Know the values for D, S₁ and S₂ to get the average time.
A number that makes a statement true is the solution
The origins of algebra can be traced to the ancient Babylonians, who developed a positional number system that greatly aided them in solving their rhetorical algebraic equations.

Answer:
Total distance cover by car = 253.45 km (Approx.)
Step-by-step explanation:
Given:
Speed of car = 45 km/h for 3¾ hour
Distance cover in next 2 hour = 84.7 km
Find:
Total distance cover by car
Computation:
Distance = Speed x time
Distance cover by car = 45 x 3¾
Distance cover by car = 168.75 km
Total distance cover by car = Distance cover by car + Distance cover in next 2 hour
Total distance cover by car = 168.75 + 84.7
Total distance cover by car = 253.45 km (Approx.)
