Answer:
- speed of the first bus: 36 2/3 miles per hour
- speed of the second bus: 73 1/3 miles per hour
Step-by-step explanation:
The second bus travels twice as fast, so will take half the time of the first bus. The second bus takes 3 hours less time, so that is half the time of the first bus.
The first bus's speed is (220 mi)/(6 h) = 36 2/3 mph.
The second bus's speed is twice that: 73 1/3 mph.
B = number of boys = 8 G = number of girls The average mass of everyone is: [ (55)B + (52)G ] ⁄ (B + G) = 53.2 (55)B + (52)G = (53.2)B + (53.2)G (1.8)B = (1.2)G (1.5)B = G The ratio of girls to boys is —> 1.5 :1 If there are 8 boys, then there are 12 girls
