Bert’s salary of P38,000 a month was increase twice at the same rate. He now

5.
Romy can run at a rate of 2500 meters for every 40 minutes. Assuming that he can run at
that constant speed, what is the distance covered by him if he runs for 1 hour and 10
minutes ?

• 51K - 38K = 13K (Kunin natin kung makgano ang total increased rate niya)
• 13K ÷ 2 = 6.5K (Divided by 2 kasi equal ang dalawang magkasunod na rate na inincreased sa kanya)
• 38K + 6.5K = 44.5K ( Base pay plus first increase niya)
• 51.5K + 6.5K = 58K (Ang magiging salary niya after 3rd Increase at the same rate)

• 2500m ÷ 40min = 62.5m/min
• 70min * 62.5m/min
• 4375m

Salamat papsi itong dalawa nalang kasi hirap sagutan

38k/m ÷ 26/d= 1,461.5
51k/m ÷ 26/d= 1,9615
total increase of 2 months is 500
first increase is 1461.5+250 =1,711.5

on 3rd increase total increase/day is 750
2,211.5/d x 26days in a month =57,499

in mathematical equation
If
A is 1st month
C is 3rd month
I=?
B=for first increase
D for days
A=38k/m D=Days
C=51k/m
B=?
E=? is for 3rd increase
B=(A÷D)

E=2(B)

.
B.
40m =2500
70m = ????


D/M=625 per 10minute
625x7 = 4,375meters in 70mins
