Answer:
9:15 am
Step-by-step explanation:
Alarms sound at 7:15 am
Alarm frequencies are 40 min and 60 min
Since 40= 20*2 and 60= 20*3, the overlapping frequency is:
- 20*2*3= 120 min = 2 hours
So next time both alarms sound at 7:15 am + 2 hours = 9:15 am

Answer:
222 ft/sec

Essentially you're being asked to find the unit speed (that is, distance per sec).
1000 ft
------------ = 222 feet/sec is the approx. average speed / unit speed
4.5 sec
His total load is 4*125 + 2*75 + 2*50, which is 750
now, is that 750 95% of 800?
well 95% of anything is 95/100 * anything
thus, 95% of 800 is 95/100 * 800 or 0.95 * 800
now, is that less than more or equals to 750? if it's, then he's golden, because his load is less or equals to 95% of 800, if not, then he needs to cut down some
