The cunninghams are moving across the country. mr. cunningham leaves 33 hours before mrs. cunningham. if he averages 40mph40⁢mph and she averages 80mph80⁢mph, how long will it take mrs. cunningham to overtake mr. cunningham?

65t = 40(t+2.5)65t=40t+10025t=200t=4 Hours 

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
