Dan types at a speed of 30 keystrokes in 60 seconds. He pauses for 5 seconds after every 200 key strokes.How long would he take to type 0 to 1020 and A to Z?
(a) 100 min
(b) 101 min and 10s
(c) 101 min and 15s
(d) 101 min and 25s
I solved it this way: Total keystrokes: 1021 (because includes 0) + 26 = 1047
30 keystrokes in 1 min - so 1047 key strokes in 34.9 min
Total time : 34.9 + (5*5 - he pauses after 200 strokes each time) = 69.9
What is wrong in my solution?
A and B walk up an escalator (moving stairway).The escalator moves at constant speed,A takes six steps for every four of B's steps. A gets to the top of the escalator after having taken 50 steps ,while B(because his slower pace lets the escalator do a little more of the work) takes only 40 steps to reach the top. If the escalator were turned off,how many steps would they have to take to walk up?
a)80
b)100
c)120
d)160
